I can HELP you, but I will not do the problem for you.
There are 3 right triangles in the figure.
You should be able to prove that all 3 of them are similar.
Once you know that, the problem is straightforward.
If you can't prove similarity, please make a comment and I will help further
.
Please note: the split on the hypotenuse suggests that all 3 triangles are 3-4-5 right triangles!

Not undetermined but not 45. In fact each of the 3 right triangles is a 3-4-5 right triangle & the altitude of the large triangle is, therefore, 12.
